v CASEMENI WINDOW.

Application filed June 22, 1925.

French easement windows, bearing small panes of glass, are popular` in building construction and would be still more so were it not for the inconvenience of washing the small panes to keep them clean. One of the objects of this invention, therefore, is so to construct the window that the glass will be in one r two large lights, which can be swung on hinges far enough away from mullions on each side to allow unobstructed access to the lights for cleaning and polishing them as large panes of glass. l

A further object is to make the lights vertically adjustable to provide openings at the top or bottom of the windowfor purposes of ventilation without Swinging the window open on its hinges.

Another object is to provide fixed metal mullions on the outside of the glass, which, besides conforming in appearance to the mullioned efl'cct of the window, will constitute a barrier to repel burglars and other trcspassers.

Another object is to provide an inexpensive fly screen which can be conveniently placed and removed.

A further object is to simplify and better the construction in ways that will be hereinafter explained and the novel features thereof specified in the appended claims.

I accomplish the objects above enumerated by means of the accompanying drawing which is expressly made a part hereof and in whichi Fig. 1 is an inside elevation of my invention in closed condition, Fig. 2 is a perspective view of the same in open condition, Fig. is a vertical section on the line 3-3 of Fig. l, and Fig. l is a perspective view of a pane of glass and a portion of its mounting.

Like characters of reference indicate like parts in the several views of the drawing.

The window frame 5 is here shown as formed of a sheet metal shell with a wood filling which is set in a wall in the usual manner. It has an inner rabbet forming a shoulder 6; which acts as a stop to limit the outward adjustment of the window.

The window as a unit comprises three main separate members, i. e., an outside metal grating which has mullions 7 according to the desired pattern or design. This member is preferably fastened by screws 9, or other secure means to the frame 5 and will form a barrier against the passage of burglars or other trespassers through the Serial No. 38,648.

opening. The second member may be of wood, metal or metal filled with wood, and corresponds in dimensions with, and has mullions 8 like the mullions of grating 7 thereby to present the eii'ect when closed of a single French window with mullions. The member 10 is hinged to the frame 5, sufticiently far from the grating 7 for the assembly between the two of the third member, comprising a rectangular frame 11, preferably of hollow sheet-metal construction, as shown in Fig. Ll, which is hinged to the member 10, and will swing away from the grating 7 with the member 10, but may afterwards be swung on its own hinges away from said member 10, after releasing a catch 12. As shown, the inner vertical and bottom faces of the frame 11 are provided with a central flange 13 which divides these faces into two slideways for the same number of glass lights 14 and 15, which are enough more than half of the height of the opening in frame 11 to form an overlap, as shown. rilhe space between the lapped ends of the closed lights is closed to keep out dust and cold by a felt or other strip 16 which is cemented to one of the lights. Pivoted fingers 17 are here shown as movable for the assembly or removal of a light, and when lowered in front of the glass they form outer slide ways in which the raising and lowering of the lights is permitted, to secure ventilation without opening the window on its hinges.

Fixed flanges 18 may be used in part, or all of the way up if the top cross bar of frame 11 is recessed as shown at 19, for the insertion of the lights into their slideway through said recesses.

The lights may be balanced by weights sliding in the hollow frame attached to cords which pass over pulleys and are fastened to the lights in the usual construction of balanced sash (not shown) orthey may be raised and lowered by knobs 2O attached to the lights and passing out through slots 21 in a vertical mullion of the member 1l), or by a cord 21. My preferred method of cord attachment as illustrated best in Fig. 4, comprises a bar 22 having end hooks 28 that embrace the horizontal edges of the glass and have eye extensions 24 for the attachment of a cord. A bar 25 on a hook at one end has a threaded hole in which a screw or knob 2O is screwed. A given position of the glass is held by tightening the knob against the mullion. A wire cloth 26 is placed against the inner side ot grating 7 to eX- clude flies and other insects and is removably held by fasteners 2'?.

From the above description it is apparent that ventilation may be had by raising the bottom light or lowering the top one, or both, without opening the easement window; or the window may be swung open il:` still more air is desired. lt is also seen that the outer grating remains in position at all times, to repel interlopers, and that the opening is etlectually screened against the entrance of insects.

It is also apparent that by swinging the middle and outer hinged members away lrom each other access may be had to both sides ot the large glass lights to wash them without interference from the mullions on either side.

The inner member l0, with its mnllions, may be omitted and the member ll hinged to the trame 5, so as to swing away from the member l() for access to the outer sides ot the glass 'for washing, thereby cheapening the cost et construction and retaining most ot the advantages as well as the etliect ot the job, and instead of hinging the member 1l it may be made immovable, but with slideways therein for the two lights.

The invention is applicable to easement doors as well as to windows.

l claim:

l. ln a easement window, an outside liXed mullioned member, in Combination with an inner mullioned member having vertica,l ways, glass .lights slidingly mounted in said ways and means for removing `the mullions from the lights while cleaning the lights.

2. In a easement window, an outside lixed mullioned member, in combination with an inner mullioned member having vertical ways, lights slidingly mounted in said ways, means tor removing vthe mullions from the lights while cleaning the lights, and an insect screen of wire cloth held by and between said outside and inner members.

3. lin a easement window, an outside liXed mullioned member, in combination with an inner mullioned member having vertical glass-light receiving ways and single pane lights slidingly mounted in said ways, and means for removably assembling the inner' member relative to the outer one and the mullioned 'portions ot the inner' member from the lights whereby the members may be separated to avoid interference by their mullions with cleaning and polishing ot the glass lights.
